It turns out that my iron levels are fine. Haemoglobin is 139 g/L and serum ferritin is 74 ng/mL. The haemoglobin reading is subject to ‘sports anaemia’ which is when your haemoglobin concentration reading is a bit lower because you really have more plasma, not because you actually have less haemoglobin. Or something. There is a lot of disagreement about what a low ferritin level is, some people say 10-15, some 20, some people say that under 50 is going to impact athletic performance. But 74 is good. That’s the highest it’s ever been on a blood test.
So really, I have no excuse for my rubbish running performance lately. Since I started running after work my average easy paces have improved though. Then last week on Parkrun I ran 21:15 and this week I ran 20:55, which is a post-lockdown PB and the first time post-lockdown I’ve gone sub 21. I pretty much just threw myself at it straight from the start. I usually try to run even or negative splits but sometimes I think you just need to go out faster than comfortable and then just try to hang on when it starts getting tough. Then next week you’ll probably be able to go a bit longer before you start questioning all your life choices that led you up to the point of wanting to die somewhere in the third kilometre of a 5km run. It also helps to have a running nemesis who is slightly faster than you. Next step: sub 20?
I have to be a little bit careful with this though because I spent all of Tuesday last week feeling slightly tired, slightly irritable and slightly hungry and I’m pretty sure it was just from running a bit further and a bit faster than usual last weekend and Monday.
So I think the reason I was feeling tired before was actually just because I have a crazy adolescent dog.
